Multi-line .srt subtitle support?

I've got a foreign language film .m4v with soft-embedded .srt subtitles. (I used Subler to add the .srt track) In subtitle editors like Jubler, the subtitles are spanned across two lines. These display as two lines of dialogue in Quicktime in 10.6.2, but on my AppleTV (v 3.0.2) they display as one line, so the text ends up getting truncated with "..." on the end.

So for example:

In QT:

A brave man sheds blood
before he sheds tears.

In ATV:

A brave man sheds blood before he sheds ...

Am I using the wrong character to do a "newline"?
